What Does Nitric Oxide Do?

Nitric oxide, represented by the chemical formula NO, is a simple molecule that plays a vital role throughout the body. Despite its simplicity, this gas influences various crucial biological processes. 

Nitric oxide helps regulate blood flow, supports the immune system, assists brain function, and much more. 

This article explores nitric oxide, how our bodies produce it, and its numerous functions that contribute to our health and well-being.

What is Nitric Oxide?

Nitric oxide is a colorless gas that the body naturally produces. It’s a very simple molecule, made up of just one nitrogen atom and one oxygen atom. Despite its simplicity, nitric oxide is crucial to our body’s daily functions. It is produced by almost every cell type in the human body and is essential for promoting and maintaining health.

The production of nitric oxide takes place in the cells through a process involving enzymes called nitric oxide synthases. These enzymes help convert amino acids, the building blocks of proteins, into nitric oxide. This production is crucial for the proper functioning of blood vessels, the immune system, and the nervous system. 

Discovery and Basic Properties

Nitric oxide was discovered as a biological regulator in the 1980s, although it was known in chemistry long before that. This discovery was so significant that it led to a Nobel Prize in Physiology or Medicine in 1998. Scientists found that nitric oxide is not just a simple gas but a critical signaling molecule in the cardiovascular system.

As a molecule, nitric oxide is unique because it is a free radical. This means it has an unpaired electron, making it highly reactive and able to interact quickly with other molecules. Despite its potential for reactivity, it is stable enough within the body to carry out its roles effectively.

Nitric oxide’s basic property of being a gas allows it to diffuse rapidly across cell membranes. This ability lets it move freely between cells, transmitting signals over short distances. This quick and efficient signaling is vital for immediate responses in the body, such as expanding blood vessels to increase blood flow. Understanding these properties helps explain how nitric oxide can impact health in multiple and diverse ways.

Roles of Nitric Oxide in the Human Body

Nitric oxide has several key roles in maintaining the health and function of various body systems. Here are some of the most important:

Cardiovascular Health

One of nitric oxide’s most critical functions is regulating blood pressure. It does this by signaling the muscles in the walls of blood vessels to relax, which widens the vessels and allows blood to flow more freely. This helps maintain a healthy blood pressure level and promotes good circulation.

Immune System

Nitric oxide is also important for the immune system. It acts as a defense mechanism against infections by attacking and killing bacteria and other pathogens. Additionally, it plays a role in inflammation, which is the body’s way of healing after an injury or infection.

Nervous System

In the brain, nitric oxide is essential for communication between neurons, the cells responsible for transmitting information throughout the body. This signaling is crucial for learning and memory.

Beyond these systems, nitric oxide influences several other functions, such as helping the lungs function properly and assisting muscle recovery after exercise. It plays a role in various signaling pathways that are essential for overall health and well-being.

Health Benefits of Increasing Nitric Oxide

Increasing nitric oxide levels in your body can lead to several health benefits. Here’s how you can boost nitric oxide and take advantage of its benefits:

Dietary Sources

Eating foods rich in nitrates and nitrites, which your body converts into nitric oxide, is one of the easiest ways to increase your levels. Beets, garlic, meat, dark chocolate, leafy greens like spinach, and citrus fruits are excellent sources. These foods help enhance nitric oxide production and offer other health benefits as well.

Lifestyle and Exercises

Regular physical activity can boost nitric oxide production, especially cardiovascular exercises such as running, cycling, and swimming. Exercise increases blood flow, which stimulates the release of nitric oxide from the lining of the blood vessels. Additionally, getting enough sunlight is important as it can naturally increase nitric oxide levels.


Supplements, such as L-arginine and L-citrulline, can help raise nitric oxide levels. The body uses these amino acids to produce nitric oxide. Before starting any supplement, it’s crucial to consult with a healthcare provider to ensure it is appropriate for your health needs and to understand the proper dosage.

Risks and Considerations

While increasing nitric oxide can have many benefits, it’s important to consider the potential risks and take precautions under certain conditions.

High levels of nitric oxide can sometimes cause imbalances in the body. For example, excessive nitric oxide can lead to low blood pressure, which might result in dizziness or fainting. In some people, particularly those with autoimmune diseases, increased nitric oxide levels can exacerbate inflammation or other symptoms.

Individuals with certain health conditions should be cautious about increasing their nitric oxide levels. Those with heart conditions, low blood pressure, or kidney problems should consult their healthcare provider before making any changes intended to alter nitric oxide levels, including dietary changes, new exercise routines, or supplements.

Frequently Asked Questions

What does taking nitric oxide do for the body?

Taking nitric oxide, or increasing its levels through diet, exercise, or supplements, helps improve blood flow and oxygen delivery throughout the body. This can enhance exercise performance, support cardiovascular health by lowering blood pressure, boost the immune system’s ability to fight infections, and improve brain function by aiding neurotransmission.

What is the main function of nitric oxide?

The main function of nitric oxide is to act as a signaling molecule in the cardiovascular system. It helps regulate blood pressure by signaling the blood vessel walls to relax and dilate, allowing blood to flow more freely. This vasodilation is essential for maintaining heart health and efficient circulation throughout the body.

What are the side effects of nitric oxide?

While nitric oxide can be beneficial, it can also cause side effects, especially when levels are too high or if supplements are misused. Common side effects include headaches, dizziness, and low blood pressure. In some cases, excessive nitric oxide can lead to increased inflammation, which may worsen symptoms in people with autoimmune diseases or infections.

What does nitric oxide do to the heart?

Nitric oxide has several beneficial effects on the heart. It causes vasodilation, which reduces the workload on the heart by lowering blood pressure and improving blood flow. This can help prevent heart disease and reduce the risk of heart attacks. Additionally, nitric oxide helps regulate heart muscle contraction, supporting overall heart function and health.
